RE: McColo and SPAM

["Frank Bulk" <frnkblk () iname com>]

We experienced exactly no decrease with the McColo shut down a few weeks
back, even though we receive 2M+ messages per day.  It's interesting that
each service provider's spam populations are as different as they are.  Some
experienced gigantic decreases, others didn't.  And it's not like we have
just one domain.

I know MessageLabs examines spam rates per industry type.

Certainly, I have seen a perceptual, yet completely subjective increase.

I know major operators who have claimed to see a gigantic decrease.
